Format Conversion
Convert any supported input format to any supported output format,
within the same frame rate family. These three families are:
59.94, 29.97, 23.98
50, 25
60, 30, 24
Scaling
Supported in 2K/HD/SD formats
Zoom in and out
Reposition
Region of Interest (ROI)
Up-Conversion
Hardware 10-bit
Zoom 14:9: results in a 4:3 image zoomed slightly to fill a 14:9 image
with black side bars
Zoom Letterbox: results in image zoomed to fill fullscreen
Zoom Wide: results in a combination of zoom and horizontal stretch to
fill a 16:9 screen; this setting will introduce a small aspect ratio change
Down-Conversion
Hardware 10-bit
Anamorphic: fullscreen
Letterbox: image is reduced with black top and bottom added to
image area with the aspect ratio preserved
Crop: image is cropped to fit video output format
Aspect Ratio Conversion for SD to SD
Letterbox: Transforms SD anamorphic material to a letterboxed image
H Crop: Produces a horizontally stretched effect on the image;
transforms anamorphic SD to full frame
SD Pillarbox: Produces an image in the center of the screen with black
borders on the left and right sides and an anamorphized image in the
center
V Crop: Transforms SD letterbox material to an anamorphic image
1x BNC, 1x 3G-SDI output
